How to fix the integrated keyboard?

some of the letters on my keyboard (azerty) doesn't work well when i push them they activate an additionnal letter (the first on the right) it's like i push "a" i got "za" or "q" i got "sq" and this is like this for &;a;q;w.

and in a second time the disease reach the letters "z";"s";"x";"é" but the additional letter is the left one.

sometimes my laptop is really hot but i don't if the heat can cause that.

i wanna know if i can fix my keybaord and how to repair the letters and how to remove it if i have to change it.
